5, the top plate v6 and the outer wall 1 of the car defining acompartment, denoted by the numeral 7, the door post 3 extending acrossone end of the compartment 7. A

movable closure'S is provided, giving access no to the compartment 7,the closure 8 being hinged to the lower end of the wainscoting 5, asdenoted by'the numeral 9. The door is denoted generallyby the numeral 10and may be fashioned in any desired manner, it being preferable that thedoor 10 be an iron or metal structure. I adapted to slide throughthedoor post 3, the post being slotted to permit the passage of thedoor, and a groove 11 is provided upon the door post 4, in which groovethe 'free end of the door 10 is received, 0

prevent the door from bulging outwardly under the weight of the grainwithin the car. Preferably the door 10 comprises a plate 12, a top rail14, a bottom rail 15, end bars 16, an intermediate bar 17 and crossbraces 18. The door 10 is supported for sliding movement upon rollers 19carried by shafts 2 0," the ends of the shafts 20 preferably beingreceived within the bottom rails l5. The rollers 19 are adapted to movebetween the tracks'21 secured to the floor 2 within the compartment 7,the tracks 21 extendin out'of the compartment'and across t e doorway. toa. point adjacent the door post 4.- v 3 v A means is provided forholding the door housed within the compartment 7. "This to the door post3 by means of a flexible element 23. The pin 21' is adapted to beinserted through an opening 24C in the top plate 6, the lower end of thepin 21 registering in an opening 25 which is fashioned in the upper edgeof the *door 10. A por-' 'tion of one of the end bars 16 is cut away todefine a recess 1'6 in'w-hich is located a lever :member 26 pivotallysup orted upon the I door as indicated at 27, t e inner end of the lever26 terminating in a cam 27, adapted to engage the pin 21.

When the lever 26 is swung into a dependingposition, the cam 28, Will engage with the pin 21 thusholding the pinfixed against displacement. Moreover, when the lever 26 is thus engagedWith the pin, the lever cannot swing and clatter about.

If desired the door 10 may be equipped with an auxiliary door 50,-Whichdoor 50 may be opened When the door 10 is closed, for the purpose ofrelieving the pressure of the grain against the door 10, so that thesame may be moved to an open position.

Having thus described the invention, What is claimed is In a device ofthe class described, a supporting structure provided with a compartment;a door mounted to slide into the compartment; a pin in'sertible into thecompartwent, there being an opening in the door, in Which opening thepin is adapted to be received; and a lever pivoted to the door andadapted to protrude beyond the door to constitute a mea'nsfor moving thedoor, the
